PAPER- CONTAINER.

Application filed March 4, 1920. Serial No. 363,228.

To all whom it may concern:

Be it known that I, AMnono OBIOI, a citizen of the United States,residing at Suffolk, in the county of Nansemond, State of Virginia, haveinvented certain new and useful Improvements in Paper Containers, ofwhich the following is a description, reference being hadto theaccompanying drawing and to the figures of reference marked thereon.

container formed with a foldable closing flap, which, when sealed,provides a closed paper receptacle.

Referring more particularly to the accompanying drawings Figure 1represents an ordinary piece of paper, the diagonal thereof indicatingthe line On which it is folded;

Fig. 2 shows the paper thus folded, the dotted vertical line indicatingthe line on which one of the apices is folded inwardly; Fig. 3 shows thenext step, such apex having been folded inwardly the dotted line indicating the point at which the other diagonal apex is folded inwardly;

Fig. 4 shows these diagonal or base apices interfolded in position;

Fig. 5 is a perspective of the rear face of the container showing thedouble upstanding flaps before one of the same is folded downwardly Fig.6 shows one of such flaps folded and sealed in position, forming acomplete container; and

Fig. 7 is a sectional view on the line 77 of Fig. 6.

In general, the invention embraces an envelop type of paper containercomprising 7 an open mouth receptacle provided with an integral foldablesealing flap, made by folding a square piece of paper diagonally to forma double triangle, next folding inwardly the apices of the triangleadjacent the diagonal into overlapping position so that the apex of onewill lie within the double fold of the other,

then folding inwardly one of the remaining apices of the originaltriangle, so that the edges thereof substantially meet the edges of theinwardly folded apices leaving the other apex of the remaining triangle,which will form the closing flap, in its original upstanding position,then securing in position the inwardly folded portions or apices wherebyto form the container described. This container may then be filled asdesired, the flap folded down and sealed.

The container is made by folding a sub stantially square sheet 1 ofpaper of any size, along the diagonal indicated in dotted lines at 2 toform a double triangle having the folds 8 and 4. With the diagonal 2 asa base, the base or diagonal apices 5 and 6 are folded inwardly alonglines transverse to the diagonal, such lines being indicated in dottedlines in Fig. 2 at 7 and in dotted lines in Fig. 3 at 8, and beingpreferably at points substantially one-third the length of the base ordiagonal. These inwardly folded base or diagonal apices 5 and 6 are nextinterfolded as shown in Figs. l and 5 by inserting the apex of onewithin the double fold of the other to hold them in position. As shownin Fig. 5, the container has now as .sumed a rectangular shape,preferably square, with two upstanding triangular flaps 9 and 10integral with the body. These flaps 9 and 10 are in fact the flaps ofthe remaining apex of the original triangle shown in Fig. 2, that is tosay, these flaps 9 and 10 are the folds of the only remaining apex ofthe original triangles 3 and 41 that have not been as yet folded. Therearmost one of these folds, that is, the apex 9 is now inwardly foldedto a point where its edges 11 and 12 meet or substantially meet theedges 13 and 14 of the inwardly folded apices 5 and 6 as indicated inFig. 6 and these inwardly folded portions or apices are now sealed inany desirable manner, such as by pasting the same with mucilage, or by ametal fastener, or

by a niucilage stamp, the latter being indicated at 15 in Fig. 6.

There is now completed a paper container forming an open-mouthedreceptacle provided with an integral foldable closing flap 10 which asclearly shown in Figs. 5, 6, and 7, is the only remaining apex of theoriginal triangle which has not as yet been folded. After the contentsis inserted into the container, this flap is folded inwardly to 7 closedposition and is sealed in any desired manner.

It will be noted that such a container has been formed of asubstantially square sheet of paper, without any cutting operation, and

by the simple interfolding of the parts.

Having thus described the invention, what I claim as new and desire tosecure by Letters-Patent, is

1. A finished paper container formed from a substantially square pieceof paper by folding the same diagonally into a double triangle, foldingthe 'aplces adjacent thev angular flap of single thickness forming afoldable closure therefor.

2. A "finished paper container formed from a substantially square pieceof paper by folding the same diagonally into a double triangle,-overlapping the apices by folding the same inwardly along the diagonal,interfolding such apices one within the other, folding one only of theremaining apices of the original triangle inwardly and securing suchinwardly folded apices whereby to form an open mouthed container, theother remaining apex of the original triangle forming a foldable closingflap therefor.

8. A finished paper container formed from asquare piece of paper byfoldingthe same diagonally into a double triangle, folding the apicesinwardly along the diagonal each at a point substantially one third ofthe length of said diagonal, inter-folding such apices one within theother, folding one only of the remaining-apices of the original triangleinwardly to substantially meet the edges of the interfolded apices andsecuring such inwardly folded apices in position whereby to form anopen-mouthed container the other remaining apex of, the originaltriangle forming a foldable' closing flap therefor.

In testimony whereof, I aflix my signature.
